Definitions

  • Citrus fruits in particular are very sensitive to microbiological, mostly fungal attack, by such microorganisms as Penicillium italicum (blue mold) and P. digitatum (green mold), Alternaria citri (stem end rot) etc..
  • Other fruit decay causing fungi are for example Gleosporium perennans, G. fructigenum, Penicillium expansum etc..
  • the problem is further aggravated by the fact that the spores produced on a few individual fruits attacked by fungi rapidly spread themselves through part or all of the container or storage room, thereby leading in a short time to molding and deterioration of the whole lot.
  • SOPP sodium orthophenylphenate
  • benomyl benomyl
  • thiabendazole 2-aminobutane
  • imazalil 2-aminobutane
  • imazalil or 1-[2-(2,4-dichlorophenyl)-2-(2-propenyloxy)-ethyl]-1H-imidazole has proven particularly useful.
  • citrus fruits are prior to packing sprayed with or dipped into wax-like substances wherein appropriate fungicides have been incorporated.
  • appropriate fungicides have been incorporated.
  • a thin fungicide containing wax-layer is left on the fruit peel.
  • the wax-layer reduces transpiration of the fruits, thus preventing them from losing too quickly their fresh appearance.
  • harvested fruits, and in particular citrus fruits can be effectively protected from fungal decay by individually packaging said fruits in a film of an appropriate thermoplastic polymeric material wherein an effective amount of an appropriate fungicide is incorporated, on condition that during or shortly after packaging at least part of the packaging material is temporarily heated.
  • thermoplastic materials there may be used in the process according to the invention films of such polymeric materials as are commonly used for packing food products, such as, for example, polyolefines, e.g. polyethylene, polypropylene etc. and ionomeric polyolefines.
  • polyolefines e.g. polyethylene, polypropylene etc.
  • ionomeric polyolefines e.g. polyethylene, polypropylene etc.
  • Such materials are used which have a sufficient permeability for CO 2 and other gases which are constantly produced as a result of the fruit's metabolism.
  • high and low density polyethylene films have proven particularly useful.
  • Appropriate fungicides in the above process have a good vapour phase activity without being too volatile.
  • the group of antifungal imidazole and triazole derivatives has been found extremely useful in this respect. Preferred members within this group are for example:
  • imazalil propiconazole, azaconazole and etaconazole are particularly preferred, the most preferred being imazalil.
  • the concentration of the active substance in the thermoplastic material may vary within rather wide limits, e.g. from 0.01 to 3%, preferably from 0.05 to 1 %.
  • the fruits may be wrapped with the film or, preferably, they are seal-packaged therein. In general, the space left between the film and the fruit should be kept minimal. As a consequence it is preferable to pack the fruits individually.
  • At least part of the film is heated, preferably for a short time.
  • Such heat treatment may be performed by keeping the packed fruits shortly in a hot environment or subjecting them temporarily to intense heat radiation. In any event such treatment should be kept short enough as to cause no damage to the fruits themselves.
  • part of the packaging material is heated by direct contact and most preferably this heating is at the same time intended for the sealing of the package which may be produced e.g. from sleeves or sheets of the thermoplastic film, which forms after sealing closed sacks, each preferably containing one fruit.
  • the fruits are individually packed in a film of an appropriate thermoplastic material, preferably low density polyethylene, which contains an effective concentration of the fungicide, the packing is heat-sealed and the packed fruit is subsequently subjected to more or less intense overall heating for a short time in order to cause shrinking of the plastic bag around the fruit.
  • the shrinking operation is conveniently carried out by allowing the packed fruits to pass through a heat tunnel.
  • the process according to the invention is particularly suited for the conservation of harvested fruits, it may be used to prevent microbial, in particular fungal deterioration of food products for animal and human consumption in general.
  • food products include but are not limited to cheese, especially hard cheese, processed fruits and vegetables, meat products, bread and other bakery products, pre-packed dishes and meals etc..
  • the incorporation was performed by thoroughly mixing the active ingredient together with the molten polyethylene mass. The other half of the fruits were packed in identical polyethylene film except that it did not contain imazalil. Both with the treated and non-treated films two set-ups were tested: the HDPE-bags were either closed by means of scotch tape, or by heat-sealing. In the latter case a small industrial apparatus was used which heats a 3 mm broad band of the film for a short time (about 0.8 seconds). The rest of the experiment was run at room temperature. The experiment was terminated 9 days after inoculation. At that time the degree of decay around the wound and production of conidia were rated according to the following score system:
  • LDPE low-density polyethylene
